[Direct the user to the authorization URL to get an authorization code]
[Exchange the authorization code for an access token]
[Authorize any calls to the product APIs using the access token]
[Check site access for the app]
In order to authenticate in PostMan, I used the “authorization” tab and the “get new access token” button
And then once I clicked it and I got this error page
And now I can’t get the access token to authenticate my instance.
I noticed a couple other users have had this same issue but no solution has been posted or discussed. If anyone has any advice for me or if I did something wrong, please leave some comments so I can try and troubleshoot
For OAuth 2.0 flow testing in Postman, in the Authorization tab, on the left side, choose OAuth 2.0 and *Add authorization data to * Request URL .
On the right, under Configure New Token section, set Grant Type to Authorization Code. Click the box Authorize using browser, which will display a callback URL. Take that callback URL (should be something like https://oauth.pstmn.io/v1/callback and configure your app (on the developer.atlassian.com side) to use that Postman callback URL.
Back to Postman, set:
Auth URL to https://auth.atlassian.com/authorize
Access Token URL to https://auth.atlassian.com/oauth/token
Client ID to your app’s client ID
Client Secret to your app’s client secret
Scope to include all of the scopes you need (ex: read:user:jira read:user.property:jira)
State to any value
Client Authentication to Send as Basic Auth header
And finally… press that Get New Access Token button.
